A nurse is assessing a patient who has been on bed rest for 5 days following abdominal surgery. Which assessment finding would be the priority concern related to immobility complications?
1Mild muscle weakness in the lower extremities
2Decreased appetite and mild nausea
3Unilateral leg swelling with warmth and tenderness✓ 정답
4Slight decrease in range of motion in shoulder joints
해설
Unilateral leg swelling with warmth and tenderness indicates possible DVT, a life-threatening complication of immobility requiring immediate intervention. Other findings are less urgent complications of bed rest.
Core Nursing ExplanationKey Concept Analysis: This question assesses the nurse's ability to prioritize potential complications of immobility, specifically identifying a life-threatening condition. The core theme is Deep Vein Thrombosis (DVT) as a critical complication of prolonged bed rest. The pathophysiology involves Virchow's triad: venous stasis (from immobility), endothelial injury (from surgery), and hypercoagulability (post-operative state). A clot forming in a deep vein, often in the leg, can dislodge and travel to the lungs, causing a Pulmonary Embolism (PE), which is a medical emergency.
Answer Rationale: Key Point! The finding of Unilateral leg swelling with warmth and tenderness is the classic presentation of DVT. In a post-surgical patient on bed rest, this is the priority concern because it represents an immediate threat to the patient's life if the clot embolizes. The nurse's priority action would be to notify the physician immediately, keep the patient on bed rest, and avoid massaging the affected limb to prevent dislodgement.
Distractor Analysis:
Watch out for confusion! Mild muscle weakness is a common and expected consequence of disuse atrophy from immobility. While it requires intervention (e.g., physical therapy), it is not an immediate, life-threatening concern.
Decreased appetite and mild nausea are common post-operative findings and can be related to anesthesia, pain medication (opioids), or reduced activity. They are important for nutritional status but are not the highest priority in this context.
CORRECT. This finding signals a potential DVT, a high-priority, life-threatening complication.
A slight decrease in range of motion is an early sign of contracture formation, another complication of immobility. It requires nursing interventions like passive range of motion exercises but is not an acute emergency.
Related Concepts: The nursing priority is always based on Airway, Breathing, Circulation (ABCs) and potential for life-threatening deterioration. DVT threatens circulation and can acutely compromise breathing if it leads to PE. Other immobility complications include pressure ulcers, constipation, pneumonia, and orthostatic hypotension.

Presentation
Key Differentiator
Immediate Nursing Action
Deep Vein Thrombosis (DVT)
Unilateral leg: Swelling, warmth, redness, pain
Usually one leg; risk of PE
Notify MD. Do NOT massage. Bed rest. Anticipate anticoagulants.
Cellulitis
Red, warm, tender, swollen area; may be bilateral; often with fever
More localized infection; may have spreading redness
Notify MD. Elevate limb. Administer antibiotics.
Chronic Venous Insufficiency
Bilateral leg edema, brownish skin discoloration, stasis dermatitis
Bilateral; chronic history; no acute warmth
Elevate legs, apply compression stockings.
Anatomy, Physiology & Pharmacology Points
Pathophysiology: Virchow's Triad (Stasis, Vessel Injury, Hypercoagulability) explains DVT formation. Surgery triggers all three components.
Pharmacology: First-line treatment is anticoagulation (e.g., heparin, enoxaparin, warfarin, DOACs like rivaroxaban). Nursing responsibilities include monitoring for bleeding (e.g., gums, bruising, hematuria) and ensuring proper lab monitoring (aPTT for heparin, INR for warfarin).
Recognizing signs and symptoms (unilateral leg swelling).
Knowing preventive measures for immobilized patients (early ambulation, SCDs, anticoagulants).
Prioritizing nursing actions (assess first, notify provider, do NOT massage).
Watch Out for Question Variations!
Symptom Identification → Priority Intervention: "The nurse assesses unilateral leg swelling. What is the priority action?" (Answer: Notify the physician/Rapid Response Team).
Prevention Focus: "Which order for a post-op patient is most important to prevent DVT?" (Answer: Encourage early ambulation / Apply sequential compression devices).
Medication Focus: "A patient with DVT is started on enoxaparin. The nurse should monitor for which adverse effect?" (Answer: Bleeding/Bruising).
Nursing Clinical Practice GuideClinical Scenario: You are caring for Mr. Johnson, a 68-year-old who underwent a colectomy 5 days ago. He has been reluctant to get out of bed due to pain. During your afternoon assessment, you note his left calf is visibly larger than his right, feels warm to the touch, and he reports sharp pain when you gently palpate it.
Nursing Intervention Strategy:
Assessment (Do First): Immediately assess the affected leg. Measure calf circumference bilaterally for comparison. Assess for redness. Check vital signs, especially for tachycardia, tachypnea, or decreased SpO2, which could indicate PE. Ask about sudden shortness of breath or chest pain.
Immediate Action:Key Point!Do not massage the leg. Keep the patient on bed rest with the leg elevated (unless contraindicated). Notify the physician or Rapid Response Team immediately. Your report should be clear: "Post-op day 5, new onset unilateral left calf swelling, warmth, and tenderness. Vital signs are..."
Anticipate Orders: Prepare for a stat Doppler ultrasound of the leg. Anticipate orders for anticoagulant therapy (e.g., IV heparin drip or subcutaneous enoxaparin).
Ongoing Monitoring & Safety: Once anticoagulated, implement bleeding precautions. Monitor lab values (aPTT, INR). Educate the patient to report any signs of bleeding (e.g., nosebleeds, blood in urine/stool) or new respiratory symptoms.
Patient Safety and Precautions:
Absolute Contraindication for Massage: Never massage a suspected DVT. This can dislodge the clot.
Medication Caution: When administering anticoagulants, use correct injection techniques (e.g., for enoxaparin, do not aspirate or rub the site). Double-check dosing based on renal function and weight.
Key Monitoring: Monitor for signs of PE (sudden dyspnea, chest pain, hemoptysis, hypoxia) and bleeding (gums, IV sites, stool, urine).
Site: Abdomen (at least 2 inches from umbilicus), alternate sides.
Technique: Pinch skin, insert needle at 90-degree angle, do not aspirate, inject slowly, hold for 5 seconds, release skin fold. Do not rub the site.
A Word from Your Senior Nurse
"Nursing is not just about carrying out physician orders — it's about being the frontline guardian for your patients! In clinical practice, recognizing subtle changes like unilateral leg swelling early can be the difference between treating a DVT and managing a catastrophic PE. When studying for your boards, don't just memorize 'DVT = swollen leg' — connect it to the patho (Virchow's triad), the priority (ABCs), and the real-world action (notify, don't massage). That mindset will not only earn you a great score on the NCLEX but will make you a truly confident, professional nurse who saves lives by seeing the warning signs first!"
Deep Vein Thrombosis — Formation of a blood clot in a deep vein, usually in the leg. A serious complication of immobility and surgery due to risk of pulmonary embolism.
Virchow's Triad — The three primary factors that contribute to thrombosis: venous stasis, endothelial (vessel wall) injury, and hypercoagulability.
Pulmonary Embolism — A life-threatening condition where a blood clot (often from a DVT) travels to and blocks an artery in the lungs.
Sequential Compression Devices — Pneumatic sleeves placed on the legs that intermittently inflate to promote venous return and prevent stasis, used for DVT prophylaxis.
Anticoagulation — Pharmacological therapy to prevent the extension or formation of new blood clots. Includes drugs like heparin, enoxaparin, and warfarin.
